MARTIN MURPHEY, OF BROOKLYN, NEW YORK.

EXTENSION-CORNICE.

SPECIFICATION forming part of Letters Patent No. 232,838, dated October5, 1880.

Application filed March 3, 1880.

To all whom it may concern Beit known that I, MARTIN MURPHEY, a citizenof the United States, residing at Brooklyn, in the county of Kings andState of New York, have invented certain new and useful Improvements inExtension-Cornices; and I do hereby declare the following to be afull,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersor iigures of reference marked thereon, which form a part of thisspecication.

Figure l is afront view. Fig. 2 is a top view. Fig. 3 is a rear view,and Fig. 4 is a vertical cross-section.

Corresponding parts in the several figures are denoted by like lettersof reference.

This invention relates to that class of corniceswhich are adjustable orcapable of being extended so as to iit windows of different widths; andit may be described as being an improvement on Patent No. 224,466,granted to myself' on the 10th day of February, 1880.

In my said Letters Patent the cornice is constructed of extensionpiecesprovided upon their faces with reverse grooves to receive correspondingtongues upon the rear side of the center or connecting piece. Thisconstruction is somewhat objectionable, for the reason that in order tocut the moldings to the required shape it is necessaryT to run the stuffthrough the molding-machine twice in order to form the reverse grooves.Another difficulty was sometimes experienced in properly fitting thepieces together, which by my present invention is entirely overcome.

Referring to the drawings hereto annexed, AA represent the end orextension pieces, and B the center or connecting piece, of my improvedcornice. The center-piece B is provided upon its rear side with groovesG C, facing in the same direction, to receive corresponding tongues D Dupon the front side of the extension-pieces A. This form of molding I amable to cut by a single run through the machine, thereby effecting agreat saving in the cost of production.

Another advantage gained by constructing (No model.)

thel cornices in this manner is the saving in time in putting themtogether, it having been sometimes found difficult to fit the partstogether when constructed as shown in my Patent No. 224,466.

By my present improvement the extensionpieces may be simply hung orhooked upon the center-piece, and afterward provided at their lowerinner corners with small plates E, which extend under the lower edgeofthe center piece, as clearly shown in Fig. 3, and, while permittingthe parts to be freely slid in extending or shortening the cornice,prevent the extension-pieces from dropping oft' the center-piece.

To prevent the end pieces from being accidentally drawn off thecenter-piece in extending the cornice, the said center-piece may beprovided with a longitudinal groove, F, extending nearly to the endsthereof. The extension-pieces are provided with dowels G, which work inthe said groove and prevent them from being dropped off or removed fromthe center-piece.

In my patent above alluded to the grooves are described as beingprovided upon their inner faces with strips, the object of which is toprevent friction between the sliding pieces and the injury to thepolishing or ornamentation resulting therefrom. In my presentimprovement I have discarded the said strips, but use a substitutetherefor in the shape of shoulders H, formed upon the extension-pieces AA, facing the hooks. The said shoulders serve the same purpose ofkeeping the sliding pieces slightly apart, and have the advantage ofbeing formed in a piece with the moldings.

This invention is more simple and durable and far less expensive thanany of the class that have come to my notice.

Having thus described myinvention, Iclaim and desire to secure byLetters Patent of th United Statesl. As an improvement inextension-cornices, the combination, with a centerpiece provided uponits rear side with grooves facing in the same direction, ofextension-pieces provided upon their faces with tongues adapted to catchand slide in said grooves, as set forth.
